A system for maintaining a printed circuit board in an enclosure includes at least one interposer. The circuit board and housing are coupled to one or more interposers. The interposer(s) fixedly couples to both the circuit board and the enclosure, and allows the circuit board and enclosure to maintain alignment during thermal heat expansion along a desired axis, such as between the center of the board and housing.

System for maintaining a printed circuit board in an enclosure

A method and apparatus for maintaining an alignment of a laser diode with an optical fiber is disclosed. A mounting plate is made of a first material, and mounted on the mounting plate is a first substrate made of a second material. A semiconductor laser, with a light emitting side, is mounted on the first substrate. Separated from the first substrate by a predetermined distance is a second substrate made of a third material, and mounted on the second substrate is an optical fiber. The optical fiber is mounted, such that, the optical fiber is adjacent to and aligned with the light emitting side of the semiconductor laser. The first, second, and third materials making up the mounting plate, the first substrate, and the second substrate respectively, facilitate maintenance of the alignment between the optical fiber and the light emitting side of the semiconductor laser.

A wireless sensor includes at least one capacitive plate for sensing a distance relative to an object of interest within a semiconductor-processing environment. The sensor includes an internal power source and wireless communication such that distance and/or parallelism measurements effected using the capacitive plate(s) can be provided wirelessly to an external device.
